ORGANIC COMPOUND FOR ORGANIC EL DEVICE AND USING THE SAME

The present invention provides an organic compound represented by the following formula (1). An organic electroluminescent (organic EL) device that uses the organic compound as a light-emitting body of a light-emitting layer and/or an electron transport layer and/or a hole-blocking layer, and/or the delayed fluorescence material of the light-emitting layer has good performance. A1 and A2 are acceptors and m, n, L1, L2, Y1, Y2, X1 to X5 have the same definitions as described in the present invention.

Hole transport materials including OLED applications

The composition described here comprises at least one hole-transporting compound, wherein the hole-transporting compound comprises a core covalently bonded to at least two arylamine groups, wherein the arylamine group optionally comprises one or more intractability groups. The composition can provide good film formation and stability when coated onto hole injection layers. Solution processing of hole transporting layers of OLEDs can be achieved with the composition described here. Good mobility can be achieved.

Direct access to 4,8-functionalized benzo[1,2-b:4,5-b′]dithiophenes with deep low-lying HOMO levels and high mobilities

A general methodology has been proposed for the straightforward access to 4,8-functionalized benzo[1,2-b:4,5-b′]dithiophenes (BDTs) via Pd mediated coupling reactions including Suzuki-Sonogashira coupling and carbon-sulfur bond formation reactions. This versatile platform can be used to construct a library of BDT core centred conjugated systems, featuring large fused-ring structure and good charge mobility, where a hole mobility of 0.061 cm2 V -1 s-1 is demonstrated. With the energy level fine-tuned with functionalization, the charge transporting BDTs show great potential for donor-acceptor polymers. This journal is the Partner Organisations 2014.
